The working principle of the automatic opening and closing lifting drawer is described as follows:

when the drawer needs to be opened, the motor works to drive the lead screw to rotate in situ, so that the sliding block moves forwards along the lead screw to push the drawer body to move forwards for opening; the sliding block drives the lifting seat to move forwards together through the guide rod, and the lifting seat is limited by the lifting rod and ascends along the lifting rod and the guide rod while moving forwards, so that the basket is driven to move upwards relative to the drawer body.

When the drawer is fully opened, the basket rises to the maximum height.

When the motor rotates reversely, the lead screw rotates reversely, the drawer retracts towards the inside of the cabinet body, all the parts move reversely along with the lead screw, and when the drawer is completely closed, the basket resets and falls onto the drawer body.
